Claims. (Cl. 141-67) This invention relates to tamper proof receptacles for receiving precious metal particles and more particularly to devices for receiving and storing precious metal particles produced in metal fabricating operations.

An object of this invention is to provide a locked receptacle device for receiving and storing precious metal particles which are removed from stock in a fabricating operation.

Another object of this invention is to provide a device in which a stream of air is discharged from a tube to create a suction to move metal particles from a machine into a receptacle.

One embodiment of the present invention for moving and storing metal particles produced by metal fabricating machines may include a receptacle having a plurality of screened vents and a tubular portion for carrying the metal particles from the machine to the receptacle, a tube for discharging compressed air from the end of the tubular portion into the receptacle to create a suction for moving the particles from the machine into the receptacle, and means for locking the device to the machine to prevent unauthorized removal.

Other objects and advantages of the invention will become apparent by reference to the following detailed description thereof and the accompanying drawing illustrating a preferred embodiment of the invention, in which is disclosed a front elevation of the receptacle device locked to the lower portion of a metal working die.

Referring now in detail to the drawing, a cylindrical receptacle 11 having a conical upper end 12 is secured to a tubular portion 13. The upper end of the tubular portion 13 is locked in an aperture 15 in a lower portion of a metal working die 16 or other machine part where metal particles 17 are removed from stock (not shown) in a metal fabricating operation, the aperture 15 leading to the position where the particles 17 are removed from the stock. A pin 19 having an enlarged apertured head 20 is inserted into a hole 21 in a the lower portion of the metal working die 16 and passes through a groove 23 in the upper end of the tubular portion 13 to lock the receptacle 11 to the lower portion of the die 16.

A padlock 24 of any desired type secures the apertured head 20 to an apertured lug 26 attached to the lower portion of the die 16 to prevent unauthorized removal of the locking pin 19 and the receptacle 11.

A tube 27 for carrying compressed air is secured to the cylindrical receptacle 11 with the end of the tube positioned in the lower end of the tubular portion 13 for discharging a stream of air through the conical upper end 12 and into the receptacle 11, the stream of air creating a suction to move the precious metal particles 17 from the die 16 through the aperture 15 and the tubular portion 13 into the receptacle 11. A quick detachable coupling 28 is secured to the tube 27 for rapid connection to a source of compressed air 30. The receptacle 11 has a plurality of screened vents 29 to allow the air to escape from the receptacle, the particles of metal remaining therein. A tubular guard 31 spaced from and secured to the receptacle 11 by lugs 32 protects the screened vents 20.

In preparing the receptacle for receiving precious metal particles from the die 16, the tubular portion 13 of the receptacle is inserted into the aperture 15 in the lower portion of the die 16 and the locking pin 19 is inserted through the aperture 21 and passes through the groove 23 in the tubular portion 13, thereby securing the receptacle device to the lower portion of the die 16. The padlock 24 passes through the head 20 and the lug 26 to prevent unauthorized removal of the locking pin 19 and the receptacle device.

The tube 27 carries a stream of compressed air from a source 30 and discharges it through the lower end of the tubular portion 13 into the conical upper end 12 thereby creating a suction which carries the precious metal particles 17 from the die 16 through its aperture 15 and through the tubular portion 13 into the receptacle 11, the air escaping from the receptacle 11 through the plurality of screened vents 29.

When it is desirable to empty the precious metal particles from the receptacle, the locking pin 19 is removed to unlock the receptacle device from the lower portion of the die 16 and the receptacle device is then inverted to pour out the precious metal particles 17 It is to be understood that the above-described arrange ments are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.

What is claimed is:

1. A device for receiving and storing particles produced in a fabricating machine, comprising a receptacle having a plurality of vents and a tubular portion for directing the particles from the machine into the receptacle, means for passing a stream of air through the receptacle to create a suction for moving the particles from the machine into said receptacle, means for locking the device to the machine to prevent tampering, and means secured to the receptacle for preventing access through the vents to the particles in said receptacle.

2. A device for receiving and storing particles produced in a metal fabricating machine, comprising a vented receptacle having a conical end secured to a tubular portion for directing the particles from the machine into the receptacle, a tube for discharging a stream of air through the conical end into the receptacle and through the vents for creating a suction to move the particles from the machine into the receptacle, means for locking the device to the machine to prevent tampering, and means secured to the receptacle for preventing access through the vents to the particles in said receptacle.

3. A device for receiving and storing particles produced in a metal fabricating machine, comprising a vented receptacle having a conical end secured to a tubular portion for directing the particles from the machine into the receptacle, a tube for discharging a stream of air through the conical end to create a suction for moving the particles from the machine into the receptacle, and locking means including a pin for engaging the machine and the walls of a groove in the tubular portion to lock the device to the machine.

4. A device for receiving and storing metal particles produced in a metal fabricating operation, comprising a receptacle having a plurality of screened vents and a conical end secured to a tubular portion positioned in an opening in the machine for directing the particles from the machine into the receptacle, a tube for discharging a stream of air through the conical end to create a suction for moving the particles from the machine into the re ceptacle, a pin positioned in an aperture in the machine and passing through a groove in the tubular portion to secure said tubular portion in the opening in the machine, and means for locking the pin in the aperture in the machine tov prevent unauthorized removal? of the pin and the device.

5. In: at tamper p'ro'of receptacle device for receiving panticl'esof precious metal' produced by a machine, a tube extending into the machine, an elongated receptacle attached to the outer end of the tube, a plurality of screened vents in one end of the receptacle adjacent the said tube, a protective guard opposite the said vents and spaced fromand' connected to the receptacle at predetermined positions', means for directing: a stream of air into the end of the tube adjacent the receptacle to move the precious metal particles from the machine and through the tube and into the end of the receptacle removed from the said vents, means for locking the said tube and receptacle to the machine to prevent tampering, and quickly detachable means for connecting and disconnecting the said directing means to a source of compressed air.
